[Sole abscess (Pododermatitis purulenta superficialis) in a Bactrian camel - diagnosis, treatment, and healing...

An approximately 14-year-old female Bactrian camel was referred to the University Clinic for Ruminants with left hindlimb lameness of two weeks duration. All findings of the general clinical examination were within normal limits. Orthopedic examination revealed a left supporting limb lameness score of 2 with moderate weight-shifting and reluctance to bear weight on the lateral toe at walk. The camel was sedated (0.24 mg/kg BW xylazine i.m.+1.92 mg/kg BW ketamine i.m., 0.04 mg/kg BW butorphanol) and rolled in lateral recumbency for further investigations. Sonographic examination of the cushion of the left hindlimb revealed an abscess of diameters of 11×2.3 cm impinging both digits between the sole horn and lateral and medial cushions. The abscess was opened under local infiltration anesthesia after a 5×5 cm incision at the central sole area, the abscess capsule removed with a sharp curette and the abscess cavity flushed. The wound was then bandaged. Postoperative treatment consisted of bandage changes every 5-7 days. For these procedures the camel was repeatedly sedated. At the first change the xylazine dosage was the same for surgery, and sequentially the dosage could be reduced (0.20 mg/kg BW i.m.), but finally increased for the last dressing changes (0.22 mg/kg BW i.m.). Ketamine dosages were also reduced slightly throughout the hospitalization period (1.51 mg/kg BW i.m.), enabling a reduction of the recovery period duration. After 6 weeks of regular bandage changes the wound had healed completely with a new horn layer and showing no lameness the camel could be discharged.
